Why is control necessary for a protective atmosphere?
In the sintering furnace, continuous measurement and control of furnace atmosphere is increasingly important to improve quality control, reduce costs, and comply with regulatory requirements. To continuously measure dew point and hydrogen concentration together gives the furnace operator the ability to know more accurately the furnace atmosphere composition and flow pattern. Air Products has developed a novel gas density sensor and successfully implemented it for hydrogen concentration measurement of hot zone nitrogen-hydrogen atmosphere.
